Treatment process of hospital sewage containing highly pathogenic viruses

Abstract

The invention discloses a treatment process of hospital sewage containing highly pathogenic viruses, and relates to the technical field of sewage treatment. The treatment process specifically comprises the following process steps: S1, enabling sewage to sequentially pass through a grid channel and an adjusting tank, and adding a bactericide into the adjusting tank to obtain pretreated sewage; S2,filtering the pretreated sewage through an ultrafiltration membrane pool to obtain filtered water and concentrated sewage; S3, sequentially introducing the filtered water into a hydrolysis acidification tank, an aerobic tank and an MBR membrane tank for treatment so as to obtain purified water subjected to sterilization treatment; enabling the concentrated water to flow back to the adjusting tankto be mixed with the inlet water of the grid channel, and continuously performing sterilization treatment through the adjusting tank. The preparation method has the advantage of reducing the secondaryinfection risk of the highly pathogenic viruses.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a hospital sewage treatment process containing highly pathogenic viruses. Background technique [0002] Highly pathogenic viruses refer to viruses that can cause very serious or serious diseases in humans or animals, and are relatively easy to transmit directly or indirectly between humans, animals and humans, and animals. Among them, the new coronavirus at the end of 2019 is one of them. It has been confirmed as an acute respiratory infectious disease caused by the 2019 new coronavirus infection. Because the virus is highly contagious, the virus can also spread in the feces of infected people in addition to droplets. Survival in the environment, after the advanced treatment of hospital sewage by the traditional biochemical + MBR process, the effluent quality basically meets the first-class A standard, but in the process of biochemical and advanced treatment, gas or drop...

Among them, the new coronavirus at the end of 2019 is one of them. It has been confirmed as an acute respiratory infectious disease caused by the 2019 new coronavirus infection. Because the virus is highly contagious, the virus can also spread in the feces of infected people in addition to droplets. Survival in the environment, after the advanced treatment of hospital sewage by the traditional biochemical + MBR process, the effluent quality basically meets the first-class A standard, but in the process of biochemical and advanced treatment, gas or droplets will be generated, which will become highly pathogenic virus carriers, and then cause Practitioners have exposure risks through direct contact, droplet and aerosol inhalation, etc., and the residual sludge generated also has a greater risk of secondary infection in the post-processing process, which greatly endangers people's health.
